问题如下：
With respect to efficient markets, a company whose share price changes gradually after the public release of its annual report most likely indicates that the market where the company trades is:
选项：
A. semi-strong-form efficient.
B. subject to behavioral biases.
C. receiving additional information about the company.
解释：
C is correct.
If markets are efficient, the information from the annual report is reflected in the stock prices; therefore, the gradual changes must be from the release of additional information.
考点：Efficient Capital Market And Its Forms
这里的“gradually”很重要，说明信息不是立即反应至价格的，因此市场不是有效的。价格在慢慢变化就说明还有其他信息。
但是半强有效是指所有公开信息都已披露，应该A也不能选吧？这只是一个公司的年报信息
